Attenuators

An attenuator is a device used to reduce the strength of a signal without greatly distorting its waveform. They come in two varieties: passive or active. The ATT-0291-07-HEX-02 is an active attenuator device used in many different areas of signal applications from audio to RF. It can provide up to 44dB of attenuation in 1dB increments for frequency ranges of 250Hz to 4GHz.

Application field

The ATT-0291-07-HEX-02 is designed for use in amplifiers, oscillators, transceivers and other high-frequency circuit applications. It is also used in radio frequency (RF) systems, such as cellular phone towers, for signal strength control and linear gain control. Other application fields includes WiFi, Bluetooth, military, and industrial applications.

Working principle

The ATT-0291-07-HEX-02 is an active attenuator circuit composed mainly of a series of MOSFET transistors configured in a two-stage amplifier. These two transistors perform a differential gain and attenuation of a given signal. With the use of low-voltage values and low-power consumption, the ATT-0291-07-HEX-02 attenuator can provide up to 44dB of attenuation in 1dB increments from 250Hz to 4GHz.

In addition, the ATT-0291-07-HEX-02\'s output stage has a timeout feature which prevents overheating conditions in case of a failure in the circuit. The device can be put into a safe mode that automatically turns off when the timeout condition is present. This feature is especially advantageous in applications where the output power must remain stable and prevent any kind of signal distortion or oscillations.

The ATT-0291-07-HEX-02 is easy to incorporate into existing systems. It requires just two external components for each channel and is compatible with any DC to DC converter. The output impedance is also very low, allowing it to work with any sampling-based application.

Conclusion

The ATT-0291-07-HEX-02 is a reliable and versatile active attenuator designed for use in a variety of audio, RF, and industrial applications. Its low-voltage operation and low-power consumption make it an ideal choice for applications requiring precise attenuation levels up to 44dB with only 1dB increments. The ATT-0291-07-HEX-02 also sports a timeout feature that prevents it from overloading due to circuit failure, making it an even more attractive proposition.
